DETAILED DESCRIPTION

The disclosed subject matter provides for a weight device used for personal training. The weight device may be a kettlebell, dumbbell, weight belt device or may be incorporated in a training device as a weight or additional weight, for example in a chest press exercise device, leg-press, and the like. The wobble system of the disclosed subject matter includes at least one weight. In some cases, the weight device comprises two wobbling weights, a first wobbling weight and a second wobbling weight, according to the design of the device that comprises the wobble system. For example, a dumbbell device of the disclosed subject matter comprises a first wobbling weight and a second wobbling weight, located at two opposite sides of the dumbbell device. The first wobbling weight and a second wobbling weight move rotationally around a shaft, thereby creating an extra force applied on a user of the dumbbell device or any other exercising device in which the user maneuvers a weight, for example by pushing, pressing, lifting and the like. The first wobbling weight and the second wobbling weight may weigh the same or differ, and may include between 1-5000 grams of wobbling weight to change the force applied on a user of a dumbbell comprising the wobble system of the disclosed subject matter. The size and weight of at least one weight of the wobble system may be a function of the weight of the dumbbell device, for example 12 percent of the weight of the dumbbell device. The wobbling weights may be replaceable, according to fitness or user's requirements. The first wobbling weight and the second wobbling weight may be aligned or in an angle relative to one another.

FIGS. 1A and 1B show a wobble system for wobbling an exercising weight, according to some exemplary embodiments of the subject matter. The wobble system shown from a first side view 100 in FIG. 1A and from a second side 101 view in FIG. 1B.

In the first side view 100 of FIG. 1A, the wobble system comprises a power unit 102 used to generate movement of the first wobbling weight 111 and the second wobbling weight 119. The power unit 102 may be an engine, a motor, may include batteries or any other power source desired by a person skilled in the art. The power unit 102 may generate movement of a shaft 105 connecting the first wobbling weight 111 and the second wobbling weight. The first wobbling weight 111 and the second wobbling weight 119 are located in two opposite sides of the shaft 105. The power unit 102 may be fitted with a worm gear 103 and a spur gear 104 to rotate the shaft 105. In some exemplary cases, the worm gear 103 rotates the spur gear 104. The spur gear 104 is fitted with the shaft 105, such that rotation of the spur gear 104 generates rotation of the shaft 105. The shaft 105 then rotates a first plate 108 and a second plate 116 on which the first wobbling weight 111 and the second wobbling weight may be mounted respectively.

In some exemplary cases, the shaft 105 is connected to or comprises a first bearing 107 and a second bearing 106. The first bearing 107 and the second bearing 106 isolates the shaft 105 from the casing (not shown) thus allowing the wobbling system to rotate substantially free within the casing. The first bearing 107 and the second bearing 106 are configured to reduce friction once the wobble system 100 and 101 are encased.

The first wobbling weight 111 and the second wobbling weight rotate around the shaft 105. In some exemplary cases, each weight of the first wobbling weight 111 and the second wobbling weight 119 is connected to a plate using a connector. In addition to the rotational movement of the plate, each weight swings around a swing housing. The first wobbling weight 111 rotates by swinging around a first swing housing 110. The first swing housing 110 is connected to the first plate 108 using a first connector 109, wherein the first connector 109 is connected to first swing housing 110. The first wobbling weight 111 may be housed within the first swing housing 110, and swings relatively to the first plate 108 using the secure connection of the first swing housing 110. The second view 101 shows the second plate 116 and a second connector 117. The second connector 117 is connected to a second swing housing 118. The second wobbling weight 119 is housed within the second swing housing 118, thus the second wobbling weight 119 relatively swings around the second plate 116 while the second wobbling weight is attached to the second swing housing 118.

In some exemplary cases, the wobble system of first side view 100 further comprises a balancing structure. The balancing structure may comprise a first spring 113 connected between a first jag 112 of the first swing housing 110 and first cleat 114 of the first plate 108. The first cleat 114 connects the first spring 113 to the first plate 108. The first spring 113 is used to balance the first wobbling weight 111 when the wobble system is moved, such that the first wobbling weight 111 is returned to its starting position as described in this figure. The second side view 101 also depicts a balancing structure shaped as a second spring 121, connected between a second jag 120 of the second swing housing 118 and a second cleat 122 of the second plate 116. The second cleat 122 connects the second spring 121 to the second plate 116. The second spring 121 is used to balance the second wobbling weight 119 when the wobble system is moved, such that the second wobbling weight 119 is returned to its starting position as described in this figure.

In some exemplary cases, the wobble system of first side view 100 further comprises a limiting element. The limiting element is used to limit the swing movement of the first wobbling weight 111 and the second wobbling weight 119 around the first swing housing 110 and second swing housing 118, respectively. In such exemplary cases, the first plate 108 further comprises a first limiting unit 115 and second limiting unit (not shown) to limit the swinging of first wobbling weight 111 relative to the first plate 108 while the first plate 108 rotates. Similarly, the second plate 116 further comprises a third limiting unit 123 and fourth limiting projection (not shown) to limit the swinging of second wobbling weight 119 relative to the second plate 116 while the second plate 116 rotates.

In some exemplary cases, the wobble system further comprises a vibrating engine. The vibrating engine may include a vibration motor 124 connected to an unbalanced weight 125. The second motor 124 is fitted with the housing of the wobble system. The vibrating motor 124 adds vibration to the wobble created using the wobble system described above.

FIGS. 2A and 2B show an actuated wobble system, according to some exemplary embodiments of the subject matter. At first rotation 201, shown in FIG. 2A, the wobble system rotates to first direction 202. At second rotation 224, shown in FIG. 2B, the wobble system rotates to second direction 213.

In the present embodiment, a rotation source (not shown) is connected to a first shaft connection 204 of a first plate 203. Various rotation sources can be used for rotating the first shaft, such as a motor, an engine, and the like. In some exemplary cases, a rotation source is used to rotate the first plate and the second plate. In such case, the shaft is not used and the dumbbell comprises two separate wobble systems.

When the first plate 203 rotates, the first wobbling weight 205 swings around a first swing housing 206. The first swing housing 206 is connected to the first plate 203 using a first connector 207.

The first rotation direction 202 of the first plate 203 swings the first wobbling weight 205 at the opposite direction of direction 202; toward a first limiting unit 208. A first spring 209, connected between a first jag 210 of the first swing housing 206 and a first cleat 211 of the first plate 203. The first spring 209 is unable to pull first swing housing 206 back to its resting position (as demonstrated in FIG. 1) as long as the rotation force generated by the rotation of the first plate 203 is stronger than its pulling force.

The relative distance that first wobbling weight 205 will divert from its resting position (as demonstrated in FIG. 1) is determined by the rotation direction 202, the rotation force versus the pulling force of the first spring 209, the location of the first limiting unit 208. The second limiting unit 212 limits the first swing housing 206 when the first plate 203 rotates against the direction 202.

At second rotation 224, disclosed in FIG. 2B, a second plate 214 rotates at a second direction 213 and a second wobbling weight 216 swings around a second swing housing 217. The second swing housing 217 is connected to second plate 214 using second connector 218.

The second direction 213 of the second plate 214 swings the second wobbling weight 216 at the opposite direction of direction 213; toward a third limiting unit 219. second spring 221, connected between second jag 220 of second swing housing 217 and second cleat 222 of second plate 214, can't pull second swing housing 217 back to its resting position (as demonstrated in FIG. 1) as long as the rotation force generated by the rotation of second plate 214 is stronger than its pulling force.

The relative distance that the second wobbling weight 216 will divert from its resting position (as demonstrated in FIG. 1) is determined by rotation direction 213, by a rotation force versus pulling force of second spring 221 and limited by the third limiting unit 219. A fourth limiting unit 223 limits the second swing housing 217 when the plate rotates opposite to second direction 213.

Each plate can be rotated at both directions 202/213. When both plates are connected, as demonstrated at FIG. 1, both plates rotate at the same direction. An inversion system can be included, rotating each plate at opposite direction.

FIGS. 3A and 3B show a wobble system operating inside a dumbbell, according to some exemplary embodiments of the subject matter. A first view 300 of the dumbbell shown in FIG. 3A discloses dumbbell housing, including a control unit 302. The control unit 302 controls preferred settings of the wobble system, for example, the rotation direction, RPM (rounds per minutes), actuation of the vibration source, timers, and other exercise features. A second view 301 of the dumbbell shown in FIG. 3B discloses a power source 303. In the embodiment of FIG. 3B, the power source 303 is one or more batteries. The power source 303 can be rechargeable and include inlet for charging; removable batteries; and the like.

FIGS. 4A and 4B show perspective cut views of a dumbbell comprising a wobble system, according to some exemplary embodiments of the subject matter. The first side view 400 of FIG. 4A shows two plates 410, 420 on two opposite ends of a shaft 430. When the shaft 430 rotates, a weight 440 connected to the plate 420 swings around a single point of connection between the weight 440 and the shaft 430. A control unit 450 may control the movement of the shaft 430. Batteries 460, 462, 464 are incorporated in the dumbbell. A first side casing 470 and a second side casing 480 are used to house the plates 410, 420. A middle casing 490 covers the shaft 430. The casings 470, 480, 490 may be of a single unit or structure. Similarly, the second side view 401 of FIG. 4B shows two plates 411, 421 on two opposite ends of a shaft 431. When the shaft 431 rotates, a weight 441 connected to the plate 421 swings around a single point of connection between the weight 441 and the shaft 431. A first side casing 471 and a second side casing 481 are used to house the plates 411, 421. A middle casing 491 covers the shaft 431. The casings 471, 481, 491 may be of a single unit or structure.

The wobble system fits inside the dumbbell, as can be seen at the first side view 400 and second side view 401, thus the wobble system add wobble movement to the user of the dumbbell, changing the forces applied on the user when exercising, when the wobble system is actuated. Additional weights can be added to the dumbbell housing, creating heavier dumbbells.

FIG. 5 shows a schematic view of a weight's additional movement generated by the wobble system on operation by a user, according to some exemplary embodiments of the subject matter;

A user of a dumbbell comprising the wobble system of the subject matter moves the dumbbell from a first location 500 to a second location 501, and vice versa. The swing movement of weights with the wobble system actuated, provides an additional force to be applied on the user of the wobble system. The direction of the additional force is disclosed in wobbly movement 502 in which the direction is of a spiral shape.

FIGS. 6A and 6B show a spiral shaped wobble system, having a weight located inside a spiral, according to some exemplary embodiments of the subject matter. In FIG. 6A, the wobble system 600 rotates on a first direction 601. The first direction 601 may be counterclockwise. The wobble system 600 comprises a spiral path in which the weight moves when a shaft connected to the wobble system rotates. The weight 603 is located at a first end of the spiral 602. The second end of the spiral 602 is towards the center of the spiral 602, depending on the size of the weight 603. The spiral may rotate using a motor, without regard to the shaft (not shown). A connector 604 connects the wobble system 600 to a dumbbell.

At first end of first spiral 602, the generated wobble is stronger than the wobble generated at a second view 605 disclosed in FIG. 6B. The second view 605 shows a weight 608 at the second end of a second spiral 607. Rotating spiral 607, using a motor (not shown) or another power unit, connected to a second connector 609 that connects the spiral to a dumbbell, slides second wobbling weight 608 along the spiral.

Each spiral end can include anchoring system, such as for example magnets, a niche, a friction surface; and the like, to position the weight during rotation of the spiral. This embodiment of the wobble system can be included with an exercise weight, as shown at previous figures.
